go to Lebowski bar in Reyjk... Cheer people on as they spin the wheel and get you some free beers passed your way. ( $25 to spin it and of course I whiffed and won nothing but 3 people in a row hit 10 beers which are about 12 bucks a piece American)

One of the funnest nights of my life was doing just that and everyone singing classic rock and dancing.
